BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 523,475, dated July 24,1894.

Application filed May 3,1894. Serial No. 509,973. (No model.)

invented certain Improvements in Bottle- Stoppers, of which thefollowing is a specification.

In the description of the said invention which follows, reference ismade to the acco mpanying drawings, forming a part hereof, and in which-Figure 1 is a sectional view of the upper part of a bottle provided withthe improved stopper. Fig. 2 is a top view of the stopper alone. Fig. 3is an exterior side view of the stopper. Fig. 4 is a View of theblankfrom which a cap, forming a part of the stopper is formed.

In my application for Letters Patent, Serial No. 497,241, filed on the18th day of January, 1894, I show and describe a bottle stopper whichconsists of a cylindrical piece of cork having its upper end and a partof the body, inclosed by an elastic cap. This cap is preferably madefrom a notched sheet metal disk which is stamped or drawn into apractically cylindrical shape around the cork, and provided with anannular groove near its upper end adapted to receive a forked extractor.Below this groove is another which, in the insertion of the stopper inthe bottle mouth or throat, receives an annular bead situated on theinner surface of the throat, and the cork is thereby held firmly inplace. The bead does not, however, prevent the withdrawal of the stopperby means of the extractor before referred to. The projecting bead .inthe bottle mouth reduces its effective size, and to elastic cap, and thegroove in the bottle mouth, but in other respects to maintain theconstruction shown in the said application.

Referring now to the drawings, A is the bottle neck, and B the head.

The stopper consists of an elastic cylinder 0, preferably of cork, andan elastic metalliccap D which incloses the upper end of the corkcylinder and a part of its body. This cap is stamped, drawn or otherwiseformed from a notched disk shown in Fig. 4, and the notches a are ofsuch character that their edges 1) stand slightly apart in the finishedcap, and thereby admit of the contraction in diameter of the cap as itis inserted in the bottle mouth. The cap has an annular bead 0 adaptedto fit into a similarly shaped groove d in the throat eof the bottle. Ithas also an annular groove f to receive a forked extracting device, thegeneral construction of which is shown in Figs. 1 and 2, in dottedlines.

The ends of the prongs of the cap are turned inward into the corkcylinder, to complete the attachment of the two elements of the stopper,and a portion of the cork below the cap is made slightly larger than theinclosed portion to form a joint by its expansion when brought intocontact with the liquid contents of the bottle or the gas arisingtherefrom.

The stopper constructed as described is forced into the mouth of thebottle until the bead c of the cap enters the annular groove 61 in thebottle mouth.

I claim as my invention In combination with a. bottle having in itsthroat an annular groove, a stopper formed of a piece of flexiblematerial and a slitted grooved cap having a bead adapted to enter thegroove in the bottle mouth, substantially as specified.
